Review on MAS Stealth Propellers DJI Air Camera & Photo and Video by Troy Coste

These props do what they say, especially in terms of dB reduction. I haven't measured the improvement in flight time, but based on my subjective observations, there is some improvement. The visibility of the props is excellent compared to the standard props. One suggestion is to include installation instructions. Two of the propellers have small markings indicating which engines they are for, but this is not explained. I just figured that's how DJI does it, so I'd try to set it up that way. The props have a rather "plasticky" feel and glossy look (DJI has a matte finish), but as far as I know this can help with performance. Good product.
